Abstract(in English) | Optical RAM buffer is vital devices for the optical packet switching. In this paper, we investigate the benefit of optical RAM buffer that employs an optical bistable device. The photonic crystal cavity realizes strong light confinement, and expected to realize an integrated one-chip all-optical memory. We evaluate the packet loss probability of optical packet switches by incorporating three characteristics introduced by the optical bistable device; size of buffer, wavelength dependency, and packet lifetime. The results show that the benefit of optical RAM buffer is significant when the offered load is low and when the number of buffering port is enough. We also investigate the impact of packet lifetime on the packet loss probability. The results show that InGaAsP-based photonic crystal cavities demonstrated in the recent paper certainly improve the packet loss probability, however, extending the packet lifetime from 150 ns to 200ns will improve the packet loss probability significantly. |
